<Prior Art> As is well known, conventionally, in waterworks, city gas, etc., various valve elements such as a sluice valve are provided in the middle of a pipe laid underground, and this valve element is used for earth pressure or for passing vehicles. In order to protect from the load and enable operation from the ground, a casing for underground structure is installed above the valve body. Then, the surroundings of the housing are backfilled and the ground surface is paved with concrete, asphalt, or the like so that the upper surface of the housing and the paving surface are aligned. However, after a long period of time, the pavement surface may be worn due to the passage of vehicles, or the upper part of the housing may project from the road surface due to ground subsidence or the like. Therefore, the pavement surface is repaired, but at this time, it is necessary to lower or raise the top surface of the housing to adjust the bulk in order to match the top surface of the housing with the new paving surface. Therefore, the applicant of the present invention has previously proposed a casing for an underground structure that enables bulk adjustment without excavating the periphery of the casing (Japanese Utility Model Publication No. 62-42998).

<Effects of the Invention> In summary, according to the present invention, the outer cylindrical body having the female screw portion raised on the inner peripheral surface and the male screw portion screwed to the female screw portion of the outer cylindrical body are raised on the outer peripheral surface. In a casing for an underground structure including a tubular body, a flange portion that is gently inclined upward toward the inner circumference is provided at an outer peripheral upper edge of the inner tubular body through a buffer portion having a gently curved surface, and the flange portion is provided. A narrow inclined surface that inclines downward toward the inner circumference is formed on the inner peripheral edge of the, and a support portion that is connected to the inclined surface to support the lid body is formed, and the lid body projects from the upper surface of the flange portion. Since the setting is made not to do so, the strength of the case is significantly increased, and even if the blade of the vehicle or the snow blower collides with the case, the vehicle, the blade, etc. can be smoothly guided to the upper surface of the case. In addition to the above-mentioned strength improvement, the casing is durable without being deformed or damaged. In addition, since the lid body does not project from the upper surface of the flange portion, there is no possibility of damaging the lid body, and it is extremely useful as a casing for underground structures especially in snowy areas. Also, since the casing according to the present invention adjusts the bulk by rotating the inner cylinder, it is not necessary to dig up the periphery of the casing, the work is extremely easy, and especially when the bulk is lowered. However, the surrounding soil does not get in the way.
